Why are encryption technologies important in the network?
1. protection of privacy
In a world in which personal data is increasingly being digitised, protecting privacy is of great importance. Encryption technologies make it possible for only authorised persons to access encrypted data. This prevents sensitive information from falling into the wrong hands.
2. prevention of data misuse
Data misuse is a major problem in the digital age. The use of encryption technologies ensures that data cannot be manipulated or stolen during transmission or storage. This makes the Risk of identity theft and other forms of data misuse.
3. security for online transactions
More and more people are carrying out their banking transactions online or making purchases on the internet. It is crucial that transactions are secure and protected. Encryption technologies such as SSL/TLS make it possible for data to be encrypted during transmission and thus protected against unauthorised access.
How do encryption technologies work?
1. symmetric encryption
In symmetric encryption, a common key is used to encrypt and decrypt the data. This key must be known to both the sender and the recipient. The disadvantage of this method is that the key must be transmitted securely, otherwise there is a risk of it falling into the wrong hands.
2. asymmetric encryption
In asymmetric encryption, two different keys are used: a public key to encrypt the data and a private key to decrypt the data. The public key can be freely distributed, while the private key must be kept secret. This method offers a higher level of security as the private key does not have to be disclosed.
3. hash functions
Hash functions are used to generate a unique checksum for a message or file. This checksum is then used to check the integrity of the message or file. If the message or file changes, the checksum also changes. This makes it possible to determine whether the data has been manipulated.
What types of encryption technologies are there?
| Encryption technology | Description of the |
|---|---|
| Asymmetric encryption | Use of public and private keys for encrypting and decrypting data |
| Symmetric encryption | Use of a shared key for encrypting and decrypting data |

| Transport Layer Security (TLS) | Protocol for the secure transmission of data via the Internet |
| Virtual Private Network (VPN) | Networkthat establishes a secure connection over the Internet between remote locations |
1. SSL/TLS
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols that are used to establish a secure connection between a web server and a web browser. These protocols allow data to be encrypted during transmission and thus protected against unauthorised access. SSL/TLS is often used for secure online transactions such as online banking or online shopping.
2. VPN
A VPN (Virtual Private Network) makes it possible to establish a secure connection between a device and a network. By using a VPN, the data is encrypted and transmitted via a secure tunnel. This prevents the data from being intercepted or manipulated by third parties. VPNs are often used to protect privacy and enable access to restricted content.
3. PGP
PGP (Pretty Good Privacy) is an encryption software that is used to encrypt emails and files. PGP uses a combination of symmetric and asymmetric encryption to protect the data. The sender encrypts the data with the recipient's public key and the recipient decrypts the data with their private key.
4 S/MIME
S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for encrypting emails. S/MIME uses asymmetric encryption to protect the data. The sender encrypts the data with the recipient's public key and the recipient decrypts the data with their private key. S/MIME also offers the option of using digital signatures to verify the authenticity of the e-mail.
What are the advantages of encryption technologies?
1. protection against hackers and cyber criminals
Encryption technologies offer effective protection against hackers and cyber criminals. Encrypting data prevents it from being intercepted or manipulated by third parties. This significantly reduces the risk of identity theft, fraud and other forms of data misuse.
